Sir Keir Starmer mistakenly called Rishi Sunak the ‘prime minister’ nine weeks after winning the election and taking the role himself.
The pair clashed over the government’s decision to suspend some arms exports to Israel during the first PMQs after summer recess on Wednesday 4 September.
In the House of Commons, Mr Sunak suggested the move “beggars belief” and asked Sir Keir to explain how Labour arrived at the decision.
Responding to the question, he said the UK worked with their allies before suggesting “the prime minister knows the framework”.
He then repeated the mistake to jeers from the benches.
